Patent FR-2009031-A1 (FR)
Title: Filtration and drying of enriched uranium fines
IPC: B01J2/16
Filed: 1969-05-21
Abstract: Slurry of U235-enriched U is pumped to a vacuum filter rotating about vertical axis, where a moving scraper takes thin layer from top of filter cake and transfers damp powder to fluidised bed by a flexible tube. Powder is separated by cyclone and filter, admitted to bed in small quantities by vane lock, dried by radiant heat and withdrawn from bed continuously or discontinuously into a refrigerated collector. Semi-continuous production of dry powder from wet slurry is automatic and requires no close attention from human operator. Safe diameter of bed and safe thickness of filter cake, dependant on degree of enrichments, cannot be exceeded when set.

Title: Filler for oil containers - has conical diffuser wall joined to jet by trough and cylindrical sections
IPC: B65B39/00
Filed: 1973-04-18
Abstract: The filler equipment delivers liquid, particularly oil, into packing containers, having a tapered diffuser nozzle extending downwards at an angle determined by the viscosity of the liquid and the interfacial tension between liquid and metal. The nozzle is mounted below a distribution jet and connected to it, and below the nozzle is a liquid drip vessel with a central opening enclosed by a raised edge. During the filling operation the liquid falls vertically in a cylindrical stream through the opening, and on shutting off the remaining drops adhere to the diffuser walls and then fall into the vessel. The conical face of the diffuser (22) is connected to the filler jet (14) by a trough-shaped section (26) followed by a cylindrical one (24). These separate the path of the cylindrical stream from that followed by the remaining drops, and aid the flow of the latter. Flow can be shut off by a valve (16) working against a set on the jet, while the cylindrical and trough sections are part of the diffuser.
Patent FR-2232642-A1 (FR)
Title: Collapsible building panels for temporary structures - is formed from rigid hinged frame covered with flexible sleeve
IPC: E04C2/38
Filed: 1973-06-07
Abstract: Rigid collapsible panel for e.g., holiday homes, garden sheds, comprises covering material (12) of plastic or canvas held rigidly on a frame composed of vertical members (13) formed from channel sections held apart by crosspieces (14, 15, 16). The number of crosspieces can be increased to suit the size of the panel and the strength requirements. Crosspieces are hinged around axes on vertical members so that when frame is folded they are hidden inside the channel. When frame is unfolded, crosspieces lock onto heads, thus ensuring rigidity. Panel is weatherproof, easily dismantled and can be transported without using lorry. A house is made by fastening several panels together and windows are provided by using a transparent cover material in place of the normal material, e.g., acrylic. Doors are formed by hinging one of the completed panels and therefore, from one basic panel element, a variety of complete structures can be formed.

Title: Subdivision of a mat of flax stems - for subsequent tying into bundles
IPC: D01B1/32
Filed: 1974-01-07
Abstract: Subdivision into portions of a continuously supplied mat of stalk-like material, esp. flax, by transporting it by means of two conveyors arranged in series to a switch which when a specific quantity of material has been accumulated sends signals to the first conveyor which is thereby brought to rest and to a timer mechanism which is started up in order to restart the first conveyor after a specific time, (t1 sec). Specif. the switch when operated by the accumulated material sends a signal to a second timer mechanism which is started up and after a certain time (t2 sec) starts up a known type of binder for tying a cord round each portion of the material.

Title: Automatic advance for engine injector pump - comprises two inertial masses guided by blocks on rotating disc
IPC: F02D1/16
Filed: 1974-01-25
Abstract: An advance mechanism comprises a plate driven by the engine while a second plate (2) drives the injector pump camshaft. The second plate has a bell shaped cylindrical shaft (7) whose top rotates close to the first plate. Two inertial masses (15, 16) have a radius of curvature almost equal to that of a skirt (14). Both have slots (33, 38) in which antifriction parallel sides blocks (40, 46) are mounted to turn on axes (41, 47). When the first plate is driven the masses are driven by the blocks mounted on the second plate. Centrifugal force causes the masses to take up a position of equilibrium against the return action of a spring.

Title: Electric powered wall mounted convector heater - has wall cooling air floor behind rear plate attached to cover hood
IPC: F24H3/00
Filed: 1974-05-27
Abstract: The heater has a rectangular metal container with shielded electrical heating resistances (31, 32) along the base. The back face of the heater is covered with a plate (17) a little way in front of the wall. The top and bottom edges of this plate are perforated with a number of air inlet holes arranged in line. The hot air escapes through louvres (14) which are directed away from the wall. The draft created by the hot air causes a flow of cold air up a wall cooling space between the plate (17) and the wall. The cold air protects the wall from burn marks. The plate (17) is fixed to the rear face (16) of a covring hood forming the rear face (16), the front face of the heater, the upper face of the heater and the side faces.

Title: Quick-curl hand-held dryer with brush head - has extra cage round brush for better heat distribution and retention
Inventor: BUHLER HARALD
IPC: A45D20/50
Filed: 1974-11-08
Abstract: The hair dryer which includes a hot-air blower leading to a brush head is provided with a cylindrical cage of heat-conductive material which encloses the brush head so that the bristles pass through the cage to protrude on the outer surface. Warm or hot air is fed into the cage from the hot air blower mechanism which is preferably housed in the hollow body forming the handle for the dryer. The hollow handle is thereby provided with a cylindrical nozzle which is extended to house the brushes and cage. The hot air is thereby directed solely onto the hair wound round the cage and held by the brush so that no heat is lost and the hair is set more quickly in shape.
